[PATCH] D142427: [ValueTracking] Add logic for tracking lowbit of (and/xor/or X, (add/sub X, Odd))

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Can you please split this into an NFC patch that splits off analyzeKnownBitsFromAndXorOr() without changing logic, and then one that implements the new folds? (D142429 <https://reviews.llvm.org/D142429> could be based on either one.)
